Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is electrical schematic diagram of the present invention.
In figure, each list of reference numerals is: U1, control module, and MCU, motor control unit, K1, open limit switch, K2, closes limit switch, J1, the relay that opens the door, J2, closed relay, H, Hall element, M, back door drive motors, TJ, timer, TD, timer.
Detailed description of the invention
Referring to Fig. 1, the present invention includes control module U1, motor control unit MCU, open limit switch K1, close limit switch K2, the relay J of opening the door 1, closed relay J2, Hall element H, back door drive motors M, in motor control unit MCU, be provided with timer TJ.
Operating principle explanation:
Multiple magnet is installed in back door rotating shaft, in back door closing process, Hall element H is output pulse signal under the effect of these magnet, because the reset terminal of the timer TJ that is arranged on motor control unit MCU inside is connected with the output of Hall element H, pulse of the every output of Hall element H all makes timer TJ reset, therefore before certain pulse makes timer TJ reset, the time value that timer TJ exports is the time interval between this pulse and a upper pulse.
The present invention is provided with secondary series of fortified passes door operation, in the normal closing process of back door, and the rotating shaft smooth rotation of back door, the pulse signal of Hall element H output fixed frequency, the time interval between two adjacent pulses can not exceed setting value.In the time that car door runs into obstruction (human body or article), the rotating speed of back door rotating shaft reduces, the time interval of Hall element H output pulse increases, the time value that timer TJ exports increases, in the time that this time value reaches setting value, motor control unit MCU judgement has human body or article to be pressed from both sides, now motor control unit MCU changes the control signal of open the door relay J 1 and closed relay J2, make back door drive motors M upset, make the back door action that stops closing the door, turn to and start secondary reopening door operation, back door just can provide a period of time to the removing (such as recalling nipped hand) of obstruction after opening an angle, the heavy open angle of concrete secondary is controlled by timer TD.This secondary series of fortified passes door operation, both can effectively protect the safety of personnel after car door drive unit and car, also can avoid unnecessary back door is opened the completely time and the operational waste that are brought with removing obstacles.
Motor control unit MCU communicates by LIN bus and control module U1, and this MCU has 512 ByteEEPROM, and key parameter that can register system prevents after power down that parameter loses and produce potential safety hazard.
Back door drive motors M is controlled by open the door relay J 1 and closed relay J2, when motor control unit MCU does not have control signal output, the two ends of back door drive motors M are respectively by the constant close contact ground connection of relay J 1 and closed relay J2 of opening the door, and motor does not rotate.In the time that motor control unit MCU receives the enabling signal that control module U1 sends, export control signal to the relay J 1 of opening the door, the constant close contact of the relay J 1 that makes to open the door disconnects, constant open contact closure, back door drive motors M forward, back door upwards overturns.In the time of the gate signal of motor control unit MCU receives that control module U1 sends pass, to closed relay J2 output control signal, the constant close contact of closed relay J2 is disconnected, constant open contact closure, back door drive motors M reversion, back door overturns downwards.
